Dental insurance usually has a yearly maximum that they will pay. They typically pay 100% on preventative services, x-rays, exams, and cleanings. 80% on basic services. 50% on major. Some insurances have a deductible. Most want you to come in every 6 months for a check up and cleaning. This saves time and money later on to catch any issues early. Waiting causes usually more money, time and discomfort. Don't wait until it hurts!
Some people feel sensitivity after they receive a filling. The tooth may be sensitive to pressure, air, sweet foods, and or cold. The most common reason for pain right after a filling is that the anesthetic wears off and that the filling is too high. This is fixed with a quick adjustment to the new filling.
